CVE-2024-31223: Fides Information Disclosure Vulnerability in Privacy Center of SERVER_SIDE_FIDES_API_URL

MediumCVSS 5.3 · v3.1—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 21/100)

  • A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
  • Public proof-of-concept code exists (Exploit-DB / GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 1.1% (FIRST EPSS); higher than 66.2% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: ethyca-fides (PyPI) 2.39.2.

Low priority for now. Upgrade to ethyca-fides (PyPI) 2.39.2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Fides is an open-source privacy engineering platform, and `SERVER_SIDE_FIDES_API_URL` is a server-side configuration environment variable used by the Fides Privacy Center to communicate with the Fides webserver backend. The value of this variable is a URL which typically includes a private IP address, private domain name, and/or port. A vulnerability present starting in version 2.19.0 and prior to version 2.39.2rc0 allows an unauthenticated attacker to make a HTTP GET request from the Privacy Center that discloses the value of this server-side URL. This could result in disclosure of server-side configuration giving an attacker information on server-side ports, private IP addresses, and/or private domain names. The vulnerability has been patched in Fides version 2.39.2rc0. No known workarounds are available.
